  • Patent number: 11146825
    Abstract: The present disclosure relates to the search of more than one K-integer best-matching blocks per block within an image, corresponding to best patches for subsequent filtering. In particular, the positions of K best-matching blocks for a template block are found within an image search area, by performing calculations of the similarity between the template block and a test block at all offset positions within a search area. The positions of K or more best-matching blocks for a non-template block are found within an image search area, by performing calculations of the similarity between the non-template block and a test block at all offset positions found as offsets of best-matching blocks for all template blocks.

  • Patent number: 10979765
    Abstract: A technique is described for improved issue reporting by a receiving device such as a set-top boxes for satellite and cable television services. In an example embodiment, the receiving device generates an issue report based on internal operational logs, captured screens and/or video of a visual output, and a recording of the user's voice that includes a description of the issue they are experiencing. This issue report can be generated as an object file that can then be transmitted, via a communications network, to an issue reporting platform for processing, for example, by a technical support representative or an automated troubleshooting system.

  • Patent number: 10917585
    Abstract: Systems and methods for facilitating transportation of an observer in a vehicle include providing video images of an environment of the vehicle from a plurality of cameras having partly overlapping field of views, detecting an orientation of the observer's head, combining the video images to provide a first video image of a first section of the environment of the vehicle, and presenting a second video image of a second section of the environment of the vehicle. The second section is a subset of the first section and corresponds to the detected orientation of the observer's head. The first section is a proper subset of the environment seen by the plurality of cameras. The detecting and presenting are repeated after a predetermined time-period that is short enough not to cause nausea for the observer.

  • Patent number: 10887625
    Abstract: A raw byte sequence payload describing a picture in slices, WPP substreams or tiles and coded using context-adaptive binary arithmetic coding is subdivided into tranches with continuing the context-adaptive binary arithmetic coding probability adaptation across tranche boundaries. Thereby, tranche boundaries additionally introduced within slices, WPP substreams or tiles do not lead to a reduction in the entropy coding efficiency of these entities. However, the tranches are smaller than the original slices, WPP substreams or tiles and accordingly they may be transmitted with a lower delay, than the un-chopped original entities. According to another aspect combinable with the first aspect, substream marker NAL units are used within a sequence of NAL units of a video bitstream to enable a transport demultiplexer to assign data of slices within NAL units to the corresponding substreams or tiles to be able to, in parallel, serve a multi-threaded decoder with the corresponding substreams or tiles.

  • Patent number: 10812820
    Abstract: Provided are methods, apparatus, and computer-readable medium for processing video data by a video coding system that implements ST 2094-10. Video data can include at least two video signals, which can be displayed at the same time in different display regions of a video frame. In various implementations, various techniques can be used to determine an association between a set of color volume parameters and a video signal, and this association can be encoded into a bitstream. Upon decoding of the bitstream, the set of color volume parameters associated with a particular video signal can be used to compress the color volume of the video signal into a range that can be displayed by a particular display device.
